Wyoming Sales Tax Rate: State vs Combined
The Wyoming state sales tax rate is 4%. Most shoppers pay more than that, because counties and cities add their own local taxes on top. The statewide average combined rate is 5.39% — a population-weighted average published by the Tax Foundation for rates as of July 1, 2026 — and the highest local rate in that table adds 3% to the state rate. A $100 purchase costs $104.00 at the state rate alone and $105.39 at the statewide average.
What Is and Isn't Taxed in Wyoming
Wyoming exempts food for domestic home consumption — most food sold at grocery stores — from sales tax; prepared food is taxable. Clothing is taxed like other goods — Wyoming has no general clothing exemption — at the 4% state rate plus any local rate. Prescription drugs are exempt from Wyoming sales tax.
How to Calculate Wyoming Sales Tax
To calculate Wyoming sales tax, multiply the purchase price by the rate that applies where you buy. For the state rate only: price × 4% = tax. For a real receipt, enter your exact combined rate in the optional field above — it is printed on local receipts and published by the Wyoming Department of Revenue; the 5.39% statewide average is only an estimate. Example: a $200 purchase at the 5.39% average = $10.78 in tax = $210.78 total.
Tips for Accurate Sales Tax Calculations
Always confirm the exact local rate for your specific city or county — the statewide average (5.39%, Tax Foundation, July 2026) is a population-weighted mean and may differ from your actual checkout rate. Large purchases like appliances or electronics are where the difference between the state-only and combined rates matters most. Keep receipts that show the tax rate used; this helps verify correct tax was charged and supports any refund claims for exempt purchases. If you are making a business purchase, check whether your state offers a sales tax exemption certificate to avoid paying tax on resale items.
